Explaining Extremity in Evaluation of Group Members Academic Article uri icon

abstract

  • A meta-analysis that included more than 1,100 effect sizes tested the predictions of three theoretical perspectives that explain evaluative extremity in social judgment: complexity-extremity theory, subjective group dynamics model, and expectancy-violation theory. The work seeks to understand the ways in which group-based information interacts with person-based information to influence extremity in evaluations. Together, these three theories point to the valence of person-based information, group membership of the evaluated targets relative to the evaluator, status of the evaluators' ingroup, norm consistency of the person-based information, and incongruency of person-based information with stereotype-based expectations as moderators. Considerable support, but some limiting conditions, were found for each theoretical perspective. Implications of the results are discussed.
